Carrie's life is in danger... didn't they already do that? Yes, they did and yet here we go again. What else? Poor Queen is detained and paranoid- check. Dar and Saul are trying to outsmart each other- check. Someone with vital information decides not to reveal it on the phone, only to be killed before he can pass it on - check, and that is such a cliche in thrillers, it has been done only a billion times.
The only novelty is Madam President-elected, played by an actress with a perennial smirk and quite arrogant enough to be credible in her unsympathetic role. But when a US President is taking advice from the likes of Carrie, you know the situation is FUBAR.
PS and if by now you still don't understand what's going on.... this is the most predictable plot ever... definitely loosing steam and running out of ideas.
